SPECIFICATION forming part 0f Letters Patent No. 522,984, dated July 1'?, 1894.

Application tiled December 22, 1893. Serial No. 494,401. (No model.)

To all whom may concern:

Be itknown that I, OTIs HOOD, a citizen of the United States, residing at Onset, in the county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Car-Couplings, of which the following is a specification.

My invention relates to improvements in that class of devices which are intended for automatically coupling railroad cars, and the object is to so construct the draw-heads and operating parts thereof, that same may be employed in connection with the draw bars, coupling-links, and pins now in general use.

My invention is clearly shown in the accompanying drawings, whereon- Figure l is a vertical-longitudinal section of two car-couplings constructed according to .my invention and showing the connectinglink in one draw-head, while in the act of engaging the other draw-head. Fig. 2 is a vertical-longitudinal section of the two couplings as when joined together by the connectinglink. Fig. 3 is a front view of my improved car-coupling with sectional view of the connecting-link, as when secured in same.

The letter A designates the draw-head having link-chamber b, provided with flaringmouth c and downwardly curved rear d, terminating in an opening, as shown atf. The upper part of the flaring-mouth c is recessed asat 7i for receiving the upwardlycurved toe fi, of a trip-lever J, the heel of which is pivoted within the opening f, as shown at i. The

trip-lever J, is provided with a longitudinally elongated vertical slot 7e, in which the coupling-pin Z, is adapted to operate, to engage the coupling-link, as hereinafter explained.

In the operation of my invention the coupling-link is held within one of the draw-heads, in a horizontal position by means of the triplever and coupling-pin thereof; while the coupling-pin of the opposite draw-head, is supported on the trip-lever of said draw-head, so that when the draw-heads are brought together, the free end of the coupling-link will strike the upwardly turned toe of the trip-lever of the opposite draw-head and by raising same cause the coupling-pin thereof to drop through the slot therein and thus engage the coupling-link, as shown in Fig. 2.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination in a car-coupler, of a drawhead having a link-chamber provided with a flaring month, a recess in the upper part of said mouth, a vertical pinl1ole in rear of the recess, a downwardly curved rear to the link-chamber, and a bottom opening thereto,

as described, with a trip-lever pivoted inthe rear of the link-chamber, said trip-lever provided with a longitudinal-vertical slot, and with an upwardly curved-toe, said toe extending to the front of the draw-head and adapted to operate in the recessed upper-portion thereof and a coupling-pin having bearings in the top and bottom of the link-chamber, and in the tri p-lever, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

OTIS HOOD.
